Default Bad fuel consumption chrysler 300

Greetings all,

Not long ago there was a fuel smell inside my car along with rough start, I thought since I didn't replace the spark plugs for 80km is what causes the issue. After changing the plugs the issue was not resolved and the fuel consumption from 700km to 400km for full tank.

Turns out that the right fuel filter was clogged and the fuel flooded under the back seat, I changed the filter and the smell went and the car performance is smoother even the carbon smell that used to come from the exhaust was cleared but is still consuming more fuel than it was before the new spark plugs. So I was wondering if you anybody have any thoughts of why is consuming so much fuel?

Chrysler 300
5.7L Petrol
Oil and Oil filter changed at 174000km

Thank you.
